Abstract (en)
[origin: US2022071659A1] Embodiments disclosed herein are directed to an intraosseous access system configured to confirm access to a medullary cavity. The system includes a driver housing, an access system including a drive train, a needle assembly rotatably coupled to the access system, and an aspiration system. The needle assembly can include a needle defining a lumen and an obturator disposed therein. The aspiration system can include a syringe or a vacutainer, coupled to the obturator. Sliding one of a plunger or a vacutainer proximally can withdraw the obturator from the needle lumen and place a vacuum in fluid communication with the needle lumen to draw a fluid flow therethrough. A portion of the aspiration system can rotate along with the needle assembly. Withdrawing the obturator can place the obturator within the syringe or the vacutainer mitigating needle stick injuries. If the medullary cavity has not been accessed, the obturator can be replaced.
